One of the reasons I jumped on the Barnes bandwagon (aside from drafting him in the pick 2 draft) is because despite playing 51% of the Warriors minutes he still holds opposing 3s to a 13.2 PER. He does this without a defensive force anywhere else on the team. Bogut should fill that void, but he hasnt regained his form yet.
I want to say he's the only true starting rookie on a playoff team, but I may be wrong.
He's also the 4th and sometimes 5th option on offense, and has retained very respectable shooting numbers despite adjusting to a new role, and a new league.
Many other people have speculated that if Barnes had been on say the Bobcats, or another team that required more out of him offensively, he would've put up much more impressive numbers.
Would've been a great move for us.
